WRAPPER non SHINGLE BUNDLES;

Application filed December This invention is an improven'ient in wrappers for shingle. bundles, and more particularly in the type of wrapper designed to cover and protect every face of the bundle.

l- Shingles or" composition material, are usually shipped in bundles of a selected number, and the bundles are bound between boards of a suitable size and character, the bundle including the boards being bound with flexible strands, such as wire ties.

This manner of'packing' provides ample protection for two opposite faces of the bundle, and prevents loss and displacement of the individual shingles. It does not how "rover protect the side and end faces, of the bundle, which are constituted by the edges of the shingles, and injury is liable to oec-ur from contact-With sharp corners, due to carelessness in handling during. transpor- 1 tation. An object of the resent invention is to provide a wrapper o. a simple and inexpensive character, by'means of which a bundle may be entirely enclosed, and. protected on" all faces.

Another object is to providein a wrapper of a size to cover all of the faces of the bundle, means integral with the wrapper for reinforcing the corners of the bundle at the points crossed by the tie wires, thereby to prevent cutting, of the wrapper and the shingles.

Another object .is to provide a wrapper of the character specified, cut or otherwise 5 formed from a web of suitable stock, with a minimum of waste.

With these and other objects in view, the invention consists in the construction and novel combination of parts fully described 4 hereinafter, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being: understood that vari ous changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departingdrom the spirit of the invention.

Fig. 10 is a perspective view of the wra ppcd bundle.

In the embodiment of the invention shown in Fig. 1, the improved wrapper, which is cut orotherwiso formed from a web of suitable stock includes four major portions indiea'tedat l, 2, 3 and 4 respectively. The portions 1 and 3 are designed to cover the sides of the bundle, while the portions 2 and 4 are designed to cover the ends, and each of the major portions has oppositely extending flaps for lappinp upon the upper and lower laces of the handle.

The portions 1 and 3 iavc. flaps 56 and 78 respectively, while the portions 2 and t have flaps 91(), ll-JQ respectively. One of the major portions, 1 in the present instance. has an extension 13 at its free end to be attached to the outer cud ol the major portion 4 to connect the blauh into a frame, which may a be collapsed or flattened as shown in Fin. 2 for shipu'icut or Fl'm'aQc. or

set up into the condition of Fig. fl; that is in carton shape. it will ho umlcrsmo l that the major portions 1,2. 3 and 4- are of a width corresponding to the depth of the shingle bundle. and they are of a length correspond inn to the faces of the bundle which they are designed to cover.

Referring to his: 3 it will b noticed that when the Frame expanded as shown in. A

Fig. 3. it forms an open l'rame with-tour flaps at each end. and the flaps at each end are adapted to beloldcd upon caclrothor.

.l'n pachiun' the "somg'le u the bottom flaps 5, 7, 9 and ll are first folded, the flaps 5-7' being: folded toa'ctllcr, aiter which the flaps 9 ll are folded onto the flaps 5- 7. The shingles indicated at 14 are placed in the open carton so termed. after which the fiaps-6 8 are iolded down upon the upper Ill) face of the bundle, and the flaps -11 upon the flaps 6-8. I

. It will be evident from the description that so packed, every face of the shingle bundle, sides, ends, top and bottom is covered. The-tie wires indicated at 15, usually two in number with shingle-s of usual size, are placed around? the ends of the wra ped bundle, the ends of the wires being twisted together as shown at 16. The applying of the wires is usually done by machinery, and

it will be evident that there is great liability to cutting of the wrapper by the wires and to-consequent injury to the shingles in the bundles. This may occur from either tight wrapping, or by handling of the bundle by means of the wires. Injury might also result from relative movement of the bundle, and the tie wires, due to loose or careless application of the wire.

In order to reduce the liability of injury to the wrapper, and to the shingles by the tie wires to a minimum, 1 provide reinforcing, means for each tie wire at each corner of the bundle crossed by the wire. the said re nforces lapping about the corners. and being integral with the wrapper so that there is no possibility of displacement of the reinforces. 1

- With .this object in view I provide each of the flaps 9, 10, 1.1 and 12 with a tab 17 at itsouter corners. The tabs 17' of the flaps 9 and 10 are taken from theanatcrial of the flaps 5, 6, 7 and 8. The tabs-170i the flaps 11 and 12 are taken from the flaps 7 and 8, and from the body of the web from which the blank is cut. The tabs 17 are of a width sufficient to allow them to lap upon the major portions 1 and 3, when the wrapper is tolded about a bundle, and they are suliiciently long to extend on both sides of the wire as shown in Fig. 5. v

"When the flaps 9 and 11 are folded down upon the flaps 5 and 7, the tabs 17'eXtend out laterally from the bundle, and when the flaps 10 and 12 are folded down, the flaps 17 at the top of the blank also stand out trom the bundle. The tabs will be pressed down into place by the operation of placing the.

tie wires, and theyprovide an efficient reinforce at each corner of the bundle for each tie wire. v

The tabs are integral with the flaps and if desired they may be set off from the fin ps by crease lines between the tabs and the flaps. The flaps 5, 6, 7, 8, 9, 10, 11 and 12 are set off from the major portions 1, 2, 3 and 4 by crease lines as shown. The blank including the crease lines and theseparating cuts may be completed in asingle operation. the crease lines being formed at the same time as the cuts. here is no Waste in stock since the tongue 13. of each blank may be formed from the malterihl between the tabs 17 at the tree ends of th flaps 11 and of the preceding' blank, which would otherwise be cut and discarded.

In the embodiment of the invention shown v in Figs. 7 to 10 inclusive, the blank includes a body portion lS'having side flaps 19 and end flaps 20, and each of the flaps 19 is provided at the edge remote from the body with a wing or extension 21 of the same length as the flap, and of approximately the same width.

The extensions 21 have an aggre width greater than that of the body 18 that when they are folded down upon a b: dle 22 of shingles resting on the body they will lap upon each other as shown is folded upon the end of the adjacent side tlap 19. These wings have integral tabs 25 at their tree corners, which are-adapted to lap aboutthe corners of the,bundle', a 1id upon the body and the;adjacent flap 21-at the positions to be occupied by the tie wires. Thus there is provided reinforcing tab on each corner-0t the bundle for each tie wire In cutting the improved blank, crease lines are provided outlining the flaps 1920.

the wings 21--24 and the tabs 23-25. These crease lines are made at the same time that the blank is cut. It will be evident fromthe description that in both embodiments of the. invention,

the reinforcing tabs are integral with the blank or wrapper. This construction is that forming the subject matter of my prior application Ser. No. 741,918, filed OctKGt-h, 1924, but'in the present, instance theTabs normally stand out from the blank in'a pa'rtially free or separated relation, so that it is not necessary to manipulate them in any manner during the wrapping. When the wrapper has been applied, the tabs normally extend beyond the corners, in position to;

move naturally into their destined relation, when the tie wires are applied.
